Abstract

An apparatus for loading and unloading a plurality of shipping containers into a carrier. The containers are arranged according to a predetermined pattern on a fixed staging unit of the apparatus. A first conveyor of the apparatus receives and transports the arranged containers from the fixed staging unit. The first conveyor is movable horizontally. A second conveyor of the apparatus receives the containers from the first conveyor and transports the containers into the carrier. The second conveyor is movable horizontally and vertically. A control unit of the apparatus controls transportation of the containers from the second conveyor into the carrier when the second conveyor is vertically moved to a predetermined position.

Claims

1. An apparatus for loading a plurality of items into a carrier, comprising:

a fixed staging unit, on which the plurality of items are arranged according to a predetermined pattern;

a first conveyor configured to receive and transport the arranged items from the fixed staging unit, the first conveyor being movable substantially horizontally;

a second conveyor operatively connected to the first conveyor, the second conveyor being configured to receive the arranged items from the first conveyor and transport the arranged items into the carrier, the second conveyor being movable substantially horizontally and vertically; and

a control unit configured to control transportation of the arranged items from the second conveyor into the carrier when the second conveyor is vertically moved to a predetermined position.

2. The apparatus according to claim 1, wherein the second conveyor comprises a first end operatively connected to the first conveyor, a second end movable substantially vertically, and a body connecting the first end and the second end.

3. The apparatus according to claim 2, wherein the second conveyor comprises a platform disposed at the second end thereof, for holding and substantially vertically moving the arranged items.

4. The apparatus according to claim 3, wherein the second conveyor comprises an arm associated with the platform, for moving the arranged items from the platform into the carrier.

5. The apparatus according to claim 4, wherein the control unit is configured to move the end platform vertically to the predetermined position based on a height of the items.

6. The apparatus according to claim 1, wherein the fixed staging unit comprises a middle section and at least a pair of legs connected by the middle section, the middle section defining a hollow space therein.

7. The apparatus according to claim 6, wherein the first conveyor comprises a platform section and a frame section, at least a portion of the platform section being received in the hollow space of the middle section of the fixed staging unit.

8. The apparatus according to claim 7, wherein the first conveyor comprises a plurality of wheels for assisting the substantially horizontal movement of the first conveyor.

9. A method of loading a plurality of items into a carrier, comprising:

arranging the plurality of items according to a predetermined pattern;

moving the arranged items to a first conveyor;

transporting the arranged items from the first conveyor to a second conveyor;

moving the first conveyor and the second conveyor substantially horizontally to access a space within the carrier;

moving the second conveyor substantially vertically to a predetermined position in the space; and

moving the arranged items from the second conveyor into the carrier.

10. The method according to claim 9, wherein the step of arranging comprises arranging the plurality of items into a row.

11. The method according to claim 9, wherein the step of moving the second conveyor substantially vertically comprises determining a position in the space based on a height of the items and moving the second conveyor substantially vertically to the position.

12. The method according to claim 9, wherein the steps of moving the first conveyor and the second conveyor substantially horizontally to access a space within the carrier and moving the second conveyor substantially vertically to a predetermined position in the space are performed prior to the step of arranging the plurality of items according to a predetermined pattern.

13. A method of loading a plurality of items into a carrier, comprising:

arranging the plurality of items into a first group and a second group according to a predetermined pattern;

moving the first group and the second group to a first conveyor;

transporting the first group from the first conveyor to a second conveyor;

stopping the first conveyor;

moving the first conveyor and the second conveyor substantially horizontally to access a space within the carrier;

moving the second conveyor substantially vertically to a first predetermined position in the space;

moving the first group from the second conveyor into the carrier;

restarting the first conveyor to transport the second group from the first conveyor to the second conveyor;

moving the second conveyor substantially vertically to a second predetermined position in the space; and

moving the second group from the second conveyor into the carrier.

14. The method according to claim 13, wherein the step of arranging the plurality of items into a first group and a second group according to a predetermined pattern comprises arranging the plurality of items into at least a first row and a second row.

15. The method according to claim 13, wherein the step of moving the second conveyor substantially vertically to a second predetermined position in the space comprises determining the second position based on a height of the items and the first predetermined potion, and moving the second conveyor substantially vertically to the second position.

16. The method according to claim 13, further comprising moving the first conveyor and the second conveyor substantially horizontally after transporting the second group from the first conveyor to the second conveyor.

17. The method according to claim 13, further comprising moving the first conveyor and the second conveyor substantially horizontally after moving the second group from the second conveyor into the carrier.

18. The method according to claim 13, wherein the steps of moving the first conveyor and the second conveyor substantially horizontally to access a space within the carrier and moving the second conveyor substantially vertically to a first predetermined position in the space are performed prior to the step of arranging the plurality of items into a first group and a second group according to a predetermined pattern.

19. The method of claim 18, wherein the step of moving the second conveyor substantially vertically to a second predetermined position in the space is performed prior to the step of restarting the first conveyor to transport the second group from the first conveyor to the second conveyor.
